Hi all.
Is it possible the "Jet" sound is the noise of gas compression plants working?,This compression also makes the gas warmer.,
These are the small plants scattered around the country, that keeps gas moving in gas pipes, the big ones, used to transfer bulk gas around, like
those put in place in the UK during the late 60's and 70's.
I assume that temperature would play a part in when the noise was heard, as I assume the colder the temperature the more heat/commpression that needs
to be added. Most of these plant are fairly small and un- noticiable,especially if you do not know what to look for, and might well be assumed to be
just a a fenced off hut.
I hope the photo shows what I mean.

According to a couple of sources,
"Compressor stations are located every 100-miles to 245-miles along main and interstate pipelines, where natural gas pressure may be pumped to
between 200-psi and 1500-psi using centrifugal compressors. These compressors may be driven by gas turbine engines, by piston engines or by electric
motors to move the gas at a typical speed of 20 miles / hour." By Harry Valentine

"Compressor Stations, as mentioned, natural gas is highly pressurized as it travels through an interstate pipeline. To ensure that the natural gas
flowing through any one pipeline remains pressurized, compression of this natural gas is required periodically along the pipe. This is accomplished by
compressor stations, usually placed at 40 to 100 mile intervals along the pipeline. The natural gas enters the compressor station, where it is
compressed by either a turbine, motor, or engine."

I also see that this occurs with oil pipe lines, which is news to me, and looking at a distribution map, there are a lot of pipelines running down the
eastern coastline, just where a lot of reports of sounds have been made?
There is one of these plants near me, well maybe a couple of miles away, and to be honest I have never heard anything, but then there are a lot of
roads and railways between so a lot of background noise, and my ears my be a little old.
Because the plants are small and usually hidden from the general view, well they are in the UK, mostly, maybe people are missing an obvious cause,
mind it may not be the only cause.
